K&F Concept Nano-X Black Diffusion 1/4 Filter pre Fujifilm X100/X100S/X100F/X100VI

The K&F Concept Nano-X Black Diffusion 1/4 Filter is a premium optical accessory designed specifically for Fujifilm X100 series cameras (X100, X100S, X100F, X100VI). It replaces the original front ring and screws directly onto the lens, providing a subtle diffusion effect that softens skin tones, reduces blemishes, and creates a dreamy, cinematic glow with lowered contrast. Ideal for portrait, landscape, street photography, and videography.

Advantages

This filter enhances your images with a professional-grade diffusion effect while maintaining high light transmission (approx. 0.5-1 stop loss). The ultra-slim aviation aluminum alloy frame ensures no vignetting, and the multi-layer Nano-X coatings provide water, oil, and scratch resistance for easy cleaning and durability.
